Great costume and makeup; especially your eyeliner and cheek shading, and you definitely have the look/peraona down, but perhaps a different background that contrasted with your haircolor would've been a better choice but that's just a personal preference.

The only real critique I could see is that your pistols have been cropped out of the picture, which; while focuses the emphasis on you, negates the pose you're taking since you have the pistols in hand.
